I know what EFM means, it an Eight-to-Fourteen Modulation that replaces each 8 bits pattern with a 14 bits one in order to have pits and lands at least 3 bits long in NRZ mode.
But what does it mean that a burner supports correct EFM encoding ?
CloneCD says :
= Drive writes regular bit patterns correctly.
= Drive writes regular bit patterns almost correctly.
- = Drive does not write regular bit patterns correctly.
I can’t make any sense of it. If a wrong EFM pattern is written on a CD, it is just a coaster.
And there is absolutely no access to EFM from outside of the box.
In EFM, a 2352 bytes sector (i.e. a raw sector with error correction included) would be 4998 bytes (each byte is replaced with 14 EFM bits + 3 parity bits).
Thanks for any technical info.
